Catalyst 3850 Series Switch Session Aware Networking with a Service Template on the ISE Configuration Example

Introduction

This document describes how to configure identity services on a Cisco Catalyst 3850 Series switch with the Session Aware Networking framework. This is a new way to configure identity services (802.1x, MAC Authentication Bypass (MAB), WebAuth) that allows for greater flexibility and functionality. It uses the Cisco Common Classification Policy Language (C3PL) along with service templates that can be stored locally or on the Cisco Identity Services Engine (ISE) server.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

• Catalyst 3850 Series Switch, Cisco IOS^® CLI
• Cisco ISE
• Identity Services (802.1x/MAB/WebAuth)

Components Used

The information in this document is based on these software and hardware versions:

• Catalyst 3850 Series Switch, Cisco IOS Version 03.03.00SE or later
• Cisco ISE Version 1.2 or later

Note: Refer to the IBNS 2.0 Deployment Guide in order to view the support matrix.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Background Information

Service templates contain a set of policy attributes that can be attached to a user session via a specific action in control policy. Two examples are presented in this document:

• MAB and a locally-defined service template used for the failure scenario.
• MAB and an ISE-defined service template used for the failure scenario.

MAB is used as the example in this document. However, it is possible to use 802.1x and/or WebAuth and build complex policies with C3PL.

Configure

Note: Use the Command Lookup Tool (registered customers only) in order to obtain more information on the commands used in this section.

Network Diagram

Both examples presented here involve a Windows PC that connects to the switch that performs MAB. The Windows MAC address is not configured on the ISE, which is why MAB fails. Then, the switch applies the policy defined in the service template.

Locally-Defined Service Template

After MAB failure, the switch applies the locally-defined service template.

Here is the flow:

1. Windows sends the Ethernet frame.
   
   
2. The switch performs MAB, and sends the RADIUS-Request towards ISE with the MAC address as a username.
   
   
3. The ISE does not have that endpoint configured, and returns RADIUS-Reject.
   
   
4. The switch activates the locally-defined template policy MAB_FAIL.

For more complete information, refer to Identity-Based Networking Services Configuration Guide, Cisco IOS XE Release 3SE (Catalyst 3850 Switches).

Here is a basic example:

aaa authorization network default group ISE 
aaa accounting identity default start-stop group ISE

Service Template Defined on ISE

Here is the flow:

1. Windows sends the Ethernet frame.
   
   
2. The switch performs MAB, and sends the RADIUS-Request towards the ISE with the MAC address as a username.
   
   
3. The ISE does not have that endpoint configured, and returns a RADIUS-Reject.
   
   
4. The switch activates the template policy MAB_FAIL with the ISE Authentication, Authorization, and Accounting (AAA)-list. The RADIUS-Request is sent with the username as the template name (MAB_FAIL) and the hardcoded password: cisco123. Also, the Cisco Attribute Value (AV) Pair is attached download-request=service-template.
   
   
5. That AV Pair forces the ISE to treat that request as a service template request. All checks for authentication and authorization rules are omitted. The ISE only checks if the authorization profile with the same name (MAB_FAIL) exists. There is no need to configure the MAB_FAIL user in the local user store. Then, the ISE returns all the attributes associated with that profile, which is the Downloadable Access Control List (DACL) in this example.
   
   
6. If the DACL is not cached on the switch, it sends another RADIUS-Request for that DACL.
   
   
7. The DACL content is returned. The switch applies the policies.

ISE Configuration

After you add the Network Access Device, the Authorization Profile is required:

It is important to check the Service Template check box, and to use the same name as the one defined on the switch.

Catalyst 3850 Series Switch Configuration

This configuration has four differences from the first example:

• The local MAB_FAIL_LOCAL policy template is removed.
  
  
• Change of Authorization (CoA) support is added.
  
  
• The ISE list for the MAB_FAIL policy template (policy configured on the ISE) is used.
  
  
• An AAA authorization list for service template retrieval is named.

Here is the configuration:

aaa new-model
!
aaa group server radius ISE
 server name ISE
!
aaa authentication dot1x default group ISE
aaa authorization network default group ISE 
aaa authorization network ISE group ISE     <--- used to retrieve
service-template
from ISE
aaa accounting identity default start-stop group ISE

dot1x system-auth-control

aaa server radius dynamic-author
 client 10.48.66.74 server-key cisco

class-map type control subscriber match-all MAB-FAIL
 match result-type method mab authoritative <--- class MAB failure
!
policy-map type control subscriber POLICY_MAB
 event session-started match-all
  10 class always do-until-failure
   10 authenticate using mab aaa authc-list ISE priority 20 <--- try MAB
   20 authenticate using mab aaa authz-list ISE priority 20
 event authentication-failure match-first
  10 class MAB-FAIL do-until-failure
   20 activate service-template MAB_FAIL aaa-list ISE replace-all <--- apply
   template
policy defined on ISE for the MAB failure

interface GigabitEthernet1/0/1
 switchport mode access
 access-session port-control auto
 mab
 spanning-tree portfast
 service-policy type control subscriber POLICY_MAB

radius server ISE
 address ipv4 10.48.66.74 auth-port 1645 acct-port 1646
 key cisco

You must configure RADIUS CoA support on the switch after you change the template (authorization profile) on the ISE, because it sends the CoA in order to update the template on the switch.

On the Catalyst 3850 Series switch, enter this command in order to verify the user session:

Method status list:
       Method           State
       mab              Authc Failed

Note that state is Failed, but that the specific template and associated DACL are applied:

3850-1#show ip access-lists                 
Extended IP access list implicit_deny_acl
    10 deny ip any any
Extended IP access list xACSACLx-IP-MAB-FAIL-ACL-528741f3 (per-user)
    1 permit icmp any any     <--- DACL from ISE

The Access Control List (ACL) is not visible under the interface:

3850-1#show ip access-lists  interface g1/0/1 in 
3850-1#show ip access-lists  interface g1/0/1    
3850-1#show ip access-lists  interface g1/0/1 out
3850-1#

It is possible to verify if ASIC (hardware) is programmed correctly:

3850-1#  show platform acl

    LE Type: Group

    Input IPv4 ACL: label 4 h/w 4 (read from h/w 4)

        BO 0x1fffffa00 [CGACL]: implicit_deny_acl
    Output IPv4 ACL: label 0 h/w 0 (Group LE and label are not linked)
    Input IPv6 ACL: label 0 h/w 0 (Group LE and label are not linked)
    Output IPv6 ACL: label 0 h/w 0 (Group LE and label are not linked)
    Input MAC ACL: label 0 h/w 0 (Group LE and label are not linked)
    Output MAC ACL: label 0 h/w 0 (Group LE and label are not linked)

Each user session that has a different DACL will have a separate entry programmed in ASIC. On the ISE, there are three separate authentications:

• Failed MAB
• Successful service template retrieval (MAB_FAIL)
• Successful DACL retrieval

Here is a closer look at the steps when you receive the request for the service template:

	11001	Received RADIUS Access-Request
	11017	RADIUS created a new session
	11022	Added the dACL specified in the Authorization Profile
	11002	Returned RADIUS Access-Accept

This clearly shows that the Authentication/Authorization rules are not processed.

When there is no correct authorization profile on the ISE, it reports:

	11001	Received RADIUS Access-Request
	11017	RADIUS created a new session
	11003	Returned RADIUS Access-Reject

Also, the Event 5400 Authentication failed message is presented, but no more details are revealed. After you create the username with the cisco123 password, the error remains the same, even when there are correct Authentication/Authorization rules. The only requirement to have that feature work correctly is to have a correct authorization profile.
